Healthy Paid Clinical Trials in Maryland

This study examines the acute impact of eating an "early" versus "late" dinner. "Early" and "late" will be customized to individuals based on the individuals' own circadian rhythms. Healthy adults will have the adults' circadian rhythm assessed by measuring the adults' dim light melatonin onset (DLMO). Based on the timing of DLMO, participants will be randomized to eating dinner before DLMO or after DLMO. The investigators will also compare the effects of delaying sleep relative to dinner time. Participants will eat meals in the laboratory and have serial plasma samples collected to examine profiles of free fatty acids, glucose, insulin, triglycerides, and oxidation of dietary fat.

The purpose of this study is to investigate the acute effects of autoregulated (AR) and non-autoregulated (NAR) blood flow restriction (BFR) bicep curls on indices of arterial stiffness. We are attempting to differentiate physiological changes with AR and NAR bicep curl exercise. Twenty adults aged 18-40 years old will undergo three treatment sessions (control (no BFR), AR BFR and NAR BFR) in a randomized order separated by one week. A familiarization session will also occur one week before starting the treatment period. Each subject will undergo a series of tests including anthropometry, ultrasonography of the carotid artery, applanation tonometry, ultrasonography of the vastus lateralis, blood pressure acquisition, body composition, and maximal strength assessments (1RM). After a familiarization session with the BFR device, subjects will perform arm curls during the three treatment sessions with 4 sets to failure with a 2 seconds concentric and 2 seconds eccentric cadence, at 20% 1RM using 60% of the supine limb occlusion pressure (LOP) with 1-minute rest intervals. Assessments will be performed immediately before and after the exercise bout during each treatment session. Two-way ANOVAs will be used to examine the effects of treatment and the treatment-order interaction on pulse wave velocity, beta-stiffness index, and augmentation index. Read Less

The purpose of the study is to: Establish and evaluate a system for collection of filgrastim-mobilized peripheral blood stem cells from National Marrow Donor Program donors (NMDP) donors Assess the safety among NMDP donors of filgrastim administration and PBSC leukapheresis Assess the safety and efficacy of filgrastim-mobilized PBSC in unrelated donor hematopoietic stem cell transplant recipients Determine the acceptability of stem cell donation by filgrastim stimulated apheresis in normal donors Read Less

This is a randomized, double-blind, placebo-controlled, dose-escalation study to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of a single dose of MT2004 following oral single and multiple ascending dose administration. Read Less
